You have the correct answer. Apply a 180 degree rotation around the point (0,2)
Reason:
We'll connect corners between figures A and B.
Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).
Draw another line from the lower right corner to the upper left corner. This line is in blue.
The red and blue lines intersect at the center of rotation (0,2)
The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.
Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.

2. Write an inequality to model purchasing a car from Dealership A with the desired add-on options and staying within your budget. Use x to represent the base price of the car. (Assume that only the base price of the car is taxed to simplify the problem.)
3. Solve for x. Explain in words what the solution to the inequality means.
4. Graph the possible base price values that are included in the solution. Please upload an image of your graph.
5. Complete 2–4 for Dealership B using the same add-on options.

The add-on optionsFor the purpose of this exercise, the add-on options to select are:
Air-conditioningSunroofGPSBluetoothPower door and windowDealership AThe total amount of the add-on options is:
Total = $1000 + $500 + $3500 + $500 + $750
Total = $6250
The inequality
This is represented using:
Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:
(1 + 6.75%) * x + 751.56 + 6250 ≤ 20000
Solve for x
We have:
(1 + 6.75%) * x + 751.56 + 6250 ≤ 20000
Evaluate the like terms
(1 + 6.75%) * x ≤ 12998.44
Divide both sides by (1 + 6.75%)
x ≤ 12176.52
The solution means that the base price of the car cannot exceed $12176.52 for dealership A

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000
So, we have:

Is -(3x + 5)^2 a perfect trinomial? Why or why not?
Answers
The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.
What is a perfect trinomial?A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.
Given that:

form.
Answers
Answer: y = [tex]\frac{1}{4}[/tex]x - 3 [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Slope-intercept form is in the form of y=mx + b where m is the slope and b is the y-intercept.
We are given the slope, so we will plug this in.
y = mx + b
y = ([tex]\frac{1}{4}[/tex])x + b
Now, we will solve for the y-intercept by plugging in the point they give us.
y = ([tex]\frac{1}{4}[/tex])x + b
(-2) = ([tex]\frac{1}{4}[/tex])(5) + b
-2 = 1.25 + b
-3 [tex]\frac{1}{4}[/tex] = b

The angle addition postulate states that if you have an angle formed by two rays, say ∠BAD, and another angle formed by two rays, say ∠DAC, then the sum of their measures is equal to the measure of the angle formed by the original rays extended to meet the rays of the second angle. In other words:

Answers
Answer:
13.994[tex]cm (5.sf)[/tex]
Step-by-step explanation:
We know that the base of the cylinder is a circular base.
So circumference of base = [tex]2\pi r[/tex]
Given [tex]2\pi r=22cm\\\\r=\frac{22}{2\pi } \\r=\frac{11}{\pi } cm\\[/tex]
Volume of a cylinder = [tex]\pi r^{2} h[/tex] = 539[tex]cm^{3}[/tex]
Substitute r into the formula for volume of cylinder.
[tex]\pi (\frac{11}{\pi } )^{2} h=539\\\pi (\frac{121}{\pi ^{2} } )h=539[/tex]
Now, we will cancel [tex]\pi[/tex] from the numerator and denominator.
[tex](\frac{121}{\pi } )h=539\\h = \frac{539}{\frac{121}{\pi } } \\h = 539 * \frac{\pi }{121} \\h = 13.994cm(5s.f)[/tex]
Answer:
Aproximated height is:
14 cm
Step-by-step explanation:
volume of a cylinder = л r² h
л = 3.1416 (aprox)
r = radius
h = height
r = circunference/2л
r = 22/(2*3.1416)
r = 3.5 (aprox)
then volume is:
539 = 3.1416 * 3.5² * h
539 = 3.1416 * 12.25 * h
539 = 38.5 * h
h = 539/38.5
h = 14 cm (aprox)
